PROGRESSIVE CAVITY PUMPS

The basis of any Progressive Cavity Single Screw Pump is a power section which usually consists of a metal rotor (n-start external helix) and a rubber stator (n+1-start internal helix). Rotation of the rotor inside the stator creates sealed cavities that progressively move from suction to discharge side of the pump producing differential pressure.

TASK: Replacement of the obsolete pump unit of some European manufacturer, while remaining all the connecting dimensions involved in the feeding of chemically active liquids with significant content of mechanical impurities.

SOLUTION: Within the framework of this task, specialists of SOLTEC ® have designed and manufactured a horizontal single-screw pump BN038S02FYYDTV with adjustable capacity from 1 to 3 m3/h and working pressure up to 6 bar, with overpressure protection and protection against work on "dry running"

The main characteristics of the screw pump unit BN038S02FYYDTV

  • Pump type - horizontal single-screw pump
  • The material of the flowing part is AISI 316Ti stainless steel
  • The material of the screw (rotor) is AISI 304 stainless steel
  • The material of the stator is oil resistant rubber NBR
  • Maximum outlet pressure - up to 6 bar
  • Capacity - from 1 to 12 m3/h
  • Protection from overpressure with using bypass scheme
  • Protection system from “dry run”
  • Seal type of the drive shaft - double mechanical
  • Engine in general industrial design
  • Variator and gear reducer by VARMEC
